If you wan t I have code to call the Openblas version as well as a
blocked version which stores the relevant matrices in<br>
blocks as recommended by Dongarra et al (but it does not seem to
be worth the effort).<br>

faster than the current<br>
ADMB code for a 2,000 x 2,000 matrix and about 4 times
slower than the Openblas<br>
code which contains optimized assembler and Fortrash. Any
suggestion for improvements<br>
would be welcome. Per usual I will hold my breath.<br>
